Mayhayley Lancaster (October 18, 1875 - November 22, 1955) was an American lawyer, political activist, midwife and teacher best known for having participated in two of Georgia's most high-profile murder trials, involving defendants Leo Frank in Marietta and John Wallace in Coweta County. She was involved in Leo Frank's defense and in the Wallace case as a witness for the prosecution.
Born Amanda Mayhayley Lancaster, she grew up in Heard County, Georgia, where she lived for most of her life.
Mayhayley Lancaster was 39 years old in 1915, during the Leo Frank case. She was one of the few public voices in Georgia to defend Frank.
Thirty-two years later, in 1947, the 71-year-old Mayhayley Lancaster took part in the Wallace trial, later described in the book Murder in Coweta County. In the 1983 made-for-TV movie of the same name, she was portrayed as a local oracle by 54-year-old June Carter Cash. Cash's real-life husband, Johnny Cash, played the key role of the persistent sheriff Lamar Potts determined to bring to justice the arrogant John Wallace (Andy Griffith).
Lancaster ran for the Georgia legislature in 1926, the first woman to do so. She ran on a platform advocating roads and railroads into rural counties, public schools, and the passage of a law that mandated that doctors must deliver babies regardless of the family's ability to pay fees. She did not win, but some of her ideas were eventually carried out.
Mayhayley Lancaster died May 22, 1955. In addition to her legal, political and educational activities, she was also described as a noted fortune teller, numbers runner and self-proclaimed "Oracle of the Ages". She is buried in the cemetery at Caney Head Methodist Church.
